    Abstract: Embodiments of the present disclosure provide a method, a user equipment, UE, a network node, and a computer program product for resource allocation for transmission of uplink control information, UCI, in a wireless communication network (100). The method is performed in a UE (102) in the wireless communication network (100). The method comprises transmitting (304) a request message to the network node (104) comprising information indicating that the UE (102) has UCI to transmit which requires one or more UCI resources. Further, the method comprises receiving (306) an indication of one or more allocated UCI resources from the network node (104) in response to the transmission of the request message. The method further comprises transmitting (308) the UCI using the one or more allocated UCI resources. Corresponding base station, UE, and computer program products are also disclosed.

    Abstract: Embodiments include methods for a user equipment (UE) operating in a radio access network(RAN) as one of a group of UEs. Such methods include receiving a group resource allocation for the group of UEs to transmit or receive data in the RAN. The group resource allocation includesresources during a plurality of occasions. Such methods also include receiving one or moreactivation indications of whether the group resource allocation is activated or deactivated for use by at least the UE. Each particular activation indication is associated with all occasions subsequent to the particular activation indication. Other embodiments include complementary methods for a RAN node, as well as UEs and RAN nodes configured to perform such methods.

    Abstract: Systems and methods are disclosed herein for transmission of Hybrid Automatic Repeat Request (HARQ) feedback for multiple Semi-Persistent Scheduling (SPS) or multiple Configured Grant (CG) transmission alignment. In one embodiment, a method performed by a wireless communication device comprises receiving N configurations, where N is an integer greater than one and the N configurations are N downlink semi-persistent scheduling, SPS, configurations or N uplink configured grant, CG, configurations. The method further comprises sending or receiving HARQ feedback for N physical uplink or downlink shared channels that are associated to the N configurations and belong to a same period, using a HARQ codebook that comprises a single HARQ acknowledgement or negative acknowledgement, ACK/NACK, for the N physical uplink or downlink shared channels. In this manner, construction of a smaller HARQ codebook is enabled, which helps in saving resources.

    Abstract: A technique for using radio resources in fixed frame periods, FFPs, (500) on a channel for radio communication in a radio network comprising a first node (100) and a second node (200) is described. Each of the FFPs (500) comprises an idle time, IT, (502) for clear channel assessment, CCA, (506) of the channel and a maximum channel occupancy time, M-COT, (504) for occupying the channel depending on the CCA (506). As to a method aspect of the technique performed by the first node (100), a method (300) comprises the step of selectively monitoring (302) the radio resources in the FFPs (500) on the channel. The selective monitoring (302) comprises refraining from monitoring a first set (602) of the radio resources, which is allocated to a first message of the second node (200) and which is partially or completely in the IT (502). Alternatively or in addition, the method (300) comprises the step of selectively transmitting (304) on the radio resources in the FFPs (500) on the channel. The selective transmitting (304) comprises refraining from transmitting on a first set (602) of the radio resources, which is allocated to a first message of the first node (100) and which is partially or completely in the IT (502).

    Abstract: Embodiments of the present disclosure provide methods and apparatus for buffer state report. A method performed at a terminal device may comprise: determining (S100) a time duration, wherein a buffer size associated with data to be transmitted during the time duration is to be predicted by the terminal device; predicting (S101) the buffer size; and transmitting (S102) a scheduling request, SR, or a buffer state report, BSR, indicating the predicted buffer size to a network node. A method performed at a network node may comprise: receiving (S201) a scheduling request, SR, or a buffer state report, BSR, indicating a predicted buffer size associated with data to be received during a time duration from a terminal device; and transmitting (S202) a grant for the data according to the received SR or BSR. The latency of data transmission from the terminal device to the network node may be reduced.

    Abstract: A method and a wireless device for determining out of order (OOO) operation are disclosed. According to one aspect, the processing circuitry is configured to, when at least one physical downlink shared channel (PDSCH) is subject to semi-persistent scheduling (SPS) determine an OOO condition that is independent of a relative timing of physical downlink control channel (PDCCH) signaling, the OOO condition being one of data transmission overlap and out-of-order hybrid automatic repeat request, HARQ, feedback. A method and wireless device for codebook construction are disclosed. According to one aspect, a method includes constructing a codebook by combining a first codebook and a second codebook, the first codebook being configured for hybrid automatic repeat request (HARQ) acknowledgment (ACK) response of dynamically scheduled physical shared channels and the second codebook being configured for HARQ-ACK response of semi-persistently scheduled (SPS) physical shared channels.
